HENRY J. LEDERER, OF OMAHA, NEBRASKA. VIBRATORY DITSTRIBUTER FORPRINTING-PRESSES.'

To all whom it may concern:

Be it known that I, HENRY J. LEDERER, a citizen of theUnited States,residing at Omaha, in the county of Douglas'and State of Nebraska, haveinvented certain new and useful Improvements in Vibratory Distributersfor Printing-Presses, of which the following is aspecification.

My invention relates to that class of inkrollers for a printing-pressknown as a "vibratory distributer, or an ink-roller having a lateral aswell as a rolling movement while coacting and making contact with one ortwo other ink-rollers.

The object of my invention is to provide a means for the attainment of alateral movement of an ink-roller mounted upon thedouble ink-roller of aGordon or similar printing-press, so that the amount of printing-inkcoming upon the surfaces of the double roller, by use of my invention,will be equalized and fully distributed thereon and will therefore 1come upon the type-surfaces in a smooth and even supply.

Another object in the attainment of this purpose is to construct thesame so that my invention will be inexpensive, comparatively Speaking,and in a manner to economize space.

With these objects in view my invention consists of a cylinder andmechanism constructed therem and thereon composmg a v1-.

bratory distributer for the above'purposes embodying novel features ofconstruction and arrangement of'parts, substantially as disclosedherein.

In the drawings like letters of reference indicate like parts throughoutthe several fig ures.

Figure 1 represents a side view of my vibratory distributer with part ofthe cylinder-walls cut away to illustrate its interior construction.Fig. 2 represents apart of the .horizontal shaft, showing the lug nandaxial extremity. Fig.3 show an end view of the 5 worm withlongitudinal shaft-chamber 0. Fig.

Patented Dec. 5, 1905 view of the cylinder-section inclosing the worm,the supporting-ring u, and lug-chamber w.

inder (1, preferably constructed of metal, with closed ends and free toroll upon a horizontal I shaft hand mount the same upon the standard 0,as shown in Fig. 6. In Fig. 6 the double ink-rollers d d are positionedin their bearings e 6 upon the roller-saddle f and are free to roll andreceive their rolling movement from friction of these rollers upon theroller-bearers, type-chase, and inking-disk used upon the Gordon pressand other printing-presses of that class, the saddle-rollers receivingtheir forward and backward movement from the driven shaft 9, and I mountmy newly-invented vibratory distributer upon .the roller-saddle fbymeans of standards 0, adjustably attached thereto by means of thescrews 5. 7t and the slots it. The shaft Z2 is squared at either end andhas its stationary bearing'upon the standards, as shown by the mortisedportion at 7' of the standard 0, and the key Z. My vibratory distributerreceives its rolling movement about its shaft-center from frictionalcontact of its outer surface with the surface of rollers cl d.

In order that my vibratory distributer may also have a lateral movementwhile revolving,

I mount'a worm m upon one end of the shaft I), as shown in Figs. 1 and 7Thisworm is constructed non-revoluble upon the shaft 6 by means of thelug n thereon, fitting within the lug-chamber w of the worm. The Wormvolving movement with the cylinder and also a corresponding lateralmovement upon the worm. I also construct within the cylinder theverticalv walls r and s integral with the shell of the cylinder andplace upon the shaft 6 the spiral springs t, and upon the ends of theworm I construct the supporting-rings u.

In operation when the roller-saddle is moved forward the .frictionuponthe roller-surface 'ofmy vibratorydistributer causes it to revolve aboutthe shaft 6 in one direction, and as the spiral ribs of the worm engagethe corresponding grooves of the cylinder-section the cylinder itself ismovedlaterally in a steady motion and continues this lateral movementuntil the grooved portion of the cylinder-section rests upon theopposite supporting-ring of the worm, at which time the lateral movementceases. but the cylinder continues to revolve so long asthe forwardmotion of the rollersaddle is continued. While resting upon thesupporting-ring in this. manner the spiral spring upon the opposite endof the worm is exerting a lateral pressure, so that the end of the wormis pressed against the engaging grooves of the cylinder-section readyfor the return sweep of the saddle, and by this continued pressure, uponcommencing the reverse or backward movement of the roller-saddle, theengagement of the spiral ribs of the worm within the grooves of thecylinder-section at the opposite end of the worm for the oppositelateral movement of the cylinder is made certain. The spiral springsthus come into alternate use to insure this lateral engagement andconsequent lateral movement first in one direction and then the reverse.The spaces 4) and v 0) within the chamber w permitaslightlateralmovement of the worm upon the shaft 6 and permit the pressure of thespiral springs to become efiective in causing the close contact of. thethreads of the worm with the grooves of the cylinder-section to producethe immediate engagement of these parts at the moment when the reversesweep of the rollersaddle begins.

It is apparent that by the use of the mechanism and the arrangement ofparts herein disclosed my vibratory distributer will have a free rollingmovement upon its shaft-center and will have a lateral'movement equal inextent to the added lengths of the worm v and cylinder-section duringeach forward or backward sweep of the saddle upon which it rides andthat the extent of the lateral movement may be varied by simplyincreasing or decreasing the lengths of the worm or cylinder-section. Itis also obvious that the contact of the engaging threads andcorresponding grooves of the worm and cylinder-section is certain at themoment of reversal in the forward and backward movement of thesaddle-roller and that there will be no locking of parts.

Since the surface of the cylinder at alltimes makes contact with andrevolves upon the su rfaces of its companion rollers and has alateralmovement, the supply of printing-ink will be equalized and uniformlyspread upon the rollers which make contact with the type. I have shownand described my invention as making surface contact with two companionink-rollers upon the roller-saddle; but it will be operative when madeto contact with a single ink-roller, and on account of the lateralmovement of the cylinder at it is evident that the operation ofspreading and equalizing the supply of ink will be certain whether upona single or double ink-roller. The mechanism in my invention is simplein construction, as is apparent, and effective for the purposesdesigned, is economical in space, and its principal Working parts beingwithin the cylinder are beyond the reach of external injury.

What I claim as my invention is 1. In a vibratory distributer for aprintingpress, a horizontal shaft, a cylinder free to roll thereon, areceiving-chamber within said cylinder, and, suitably disposed therein asection of said horizontal shaft, a \vormmounted upon the shaft adaptedto have a slidable but non-revoluble movement thereon, a groovedcylinder-section integral with the cylinder to engage the threads of theworm, means for causing and continuing the close contact of the threadsof the Worm with the grooves of the cylinder-section at the time of andafter the cylinder-section has passed beyond their plane ofengagement;said slidable movement of said worm upon the shaft being for the purposeof-causing said means to be operative in continuing said close contactof the threads of the worm with the grooves of the cylindersection atsaid time of and after said cylindersection has passed beyond their saidplane of lateral engagement; in combination with a companion ink-roller,a roller-saddle of a printing-press, and suitable means formounting saidshaft thereon.

2. The Within-described vibratory distributer, consisting of ahorizontal shaft mounted upon a roller-saddle, a cylinder, a receivingspace or chamber Within the cylinder, a worm and groovedcylinder-section within the receiving-space, said worm being mountedupon the shaft andhaving a lengthwise but nonrevoluble movement thereon,said worm and cylinder-section to be operated by therolling movement ofthe cylinder upon the shaft, and the suitably-disposed means within thereceiving-chamber for causing a continued contact of the worm-threadswith the grooves of the cylinder-section after they have passed out oftheir plane of lateral engagement; said lengthwise movement of said wormupon said shaft being for the purpose of causing said means to beoperative in continuing said contact of the worm-threads with thegrooves of the cylinder-section after they have passed out of theirplane of lateral engagement; said vibratory distributer to contact withits companion roller when mounted upon a rollersaddle of aprinting-press.

3. In a new article of manufacture, a vibratory distributer for aprinting-press, consisting of a horizontal shaft, a worm and cylindermounted upon said shaft, said cylinder being free to roll thereon, andsuitably disposed therein a grooved cylinder-section integral with thecylinder and adapted to overlap the threads of the worm, said wormlocked upon the shaft but having aslight lateral motion thereon and sodisposed that its threads engage the revolving and corresponding groovesof the cylinder-section, means for causing the close and continuedcontact ofthe threads of the worm with the grooves of thecylindersection at the time of and after the cylinder- 7 section. haspassed beyond its plane of lateral engagement with the worm-threads;saidlateral motion of said worm upon said shaft being for the purpose ofcausing said means to be operative in continuing said close contact ofthe threads of the worm withthe grooves of the cylinder-section at thetime of and i after the cylinder-section has passed beyond 7 In avibratory'distributer for a printingpress, the combination of the shaftI) mounted upon the roller-saddle f by means of the standards 0, thecylinder a mounted upon'said shaft and free'to roll thereon;thecompanion rollers d being in frictional contact with said cylinder, thereceiving-chamber within the cylinder and the thereindisposed groovedcylinder-section p, the shaft within said receiving-chamber,. thethreaded worm m nonrevolubly locked thereon, the lug n with lugchanibersw,'and spaces '0 and o therein, the
